       gF – Gram-force 
       N – Newton 
       kN – Kilonewton  
       

 

Torque units: 

        lbFin – Pound-inch 
        ozFin – Ounce-inch 
        kgFm – Kilogram-meter  
        kgFmm – Kilogram-millimeter 
        Nm – Newton-meter  
        Ncm – Newton-centimeter 

Note:

 not all sensor models display all the above units. Refer to the capacity / 

resolution table for the respective sensor series for details. 

6 Mode 

The current measurement mode. Abbreviations are as follows: 
       RT – Real Time  
       PC – Peak Compression (for force sensors) 
       PT – Peak Tension (for force sensors) 
       PCW – Peak Clockwise (for torque sensors) 
       PCCW – Peak Counter-clockwise (for torque sensors) 
See 

Operating Modes

 section for details about each of these modes 

Battery / AC 
adapter indicator 

Either the AC adapter icon or battery power icon will be shown, depending on 
power conditions. Refer to the 

Power

 section for details.  

High / low limit 
indicators 

Correspond to the programmed set points. Indicator definitions are as follows: 

 – the displayed value is greater than the upper load limit  
 – the displayed value is between the load limits 

 – the displayed value is less than the lower load limit 

9 Set 

points 

The programmed load limit values. Typically used for pass/fail type testing. 
One, two, or no indicators may be present, depending on the configuration 
shown in the 

Set Points

 menu item.
